scsi: pm80xx: Update WARN_ON check in pm8001_mpi_build_cmd()

[ Upstream commit 606c54ae975ad3af540b505b46b55a687501711f ]

Starting from commit 05c6c029a44d ("scsi: pm80xx: Increase number of
supported queues") driver initializes only max_q_num queues.  Do not use an
invalid queue if the WARN_ON condition is true.
